A tubular lock is a variation of a pin tumbler lock, where the pins are arranged in a circle facing the front of the lock and are operated by a tubular key. It was once referred to as an ACE lock, with ACE being a trademark of the Chicago Lock Company, but the generic term tubular lock is far more common these days.
Locked / Unlocked. A 'locked' mobile phone is one that has been restricted by software so that it can only be used with a single network or carrier. Locked mobile phones are usually GSM phones that use a SIM card - hence the use of the term 'SIM lock'. The reason for the lock is because mobile phones are usually heavily subsidised and carriers want to discourage people switching networks or shipping phones to other countries.
